'BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 636,160, dated October 31, 1899. Application filed. AprillZ, 1899. seminarians. on model.)

To all whom it may concern:

Be it known that I, MORRIS RANDOLPH MITCHELL, residing at J onestown, in the county of Ooahoma and State of Mississippi, have made certain new and useful Improvements in Baling-Presses, of which the following is a specification.

My invention is an improvement in cotton and other presses, whereby the weight of the bales can be regulated during course of formation or packing in order to secure approximate uniformity in the weight of the bales; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of the invention as embodied in what is known as a revolving-box press. Fig. 2 is a sectional view on about line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of the inner face of one side of the box, showing the yielding dogs and the fixed stop-blocks. Fig. 4c is a detail perspective view illustrating the weighing-bars and the notched cross-bars. Figs. 5 and 5 illustrate the alarm mechanism, and Figs. 6 and 7 illustrate the invention embodied in a single-box press.

My invention is applicable to both up and down packing single and revolving box presses and to other presses to which it may be adapted. Its purpose, as before suggested, is to weigh the lint as it is put in the press by the pressure exerted by the tramper in forcing it downon or up against the block or movable end piece, and by the consequent recession of the springs supporting such end piece to notify the operator either by ringing a bell or by other suitable signal, so the operation of tramping may be stopped when the desired weight of bale is secured.

In the accompanying illustration I have shown my invention in Figs. 1 to 5, inclusive, as adapted for embodiment in what is known as a revolving-box press, while Figs. 6 and 7 illustrate the invention in a singlebox up-packing press.

In the form of press shown in Fig. lthe construction, exceptas hereinafter specified,

may be thatusually employed in such form of press. By my invention I provide at each end of the box iron guide-bars A, which project beyond the sides of the box and have the inner faces of their extensions A notched or grooved at ato receive the ends of the weighingbars B, which extend along the outer sides of the box 0, as shown. These weighing-bars B are provided with lugs b, which project through slots G into the box 0 and form supports for the movable end or false block D, which rests upon the lugs 17, as shown. The weighing-bars being depressible and supporting the false block D, such block D may be depressed as the operation of tramping proceeds until the false block rests upon the stop-blocks D within the baling-box. The weighing-bars rest upon springs E, which bear at their lower ends upon metal plates F, secured upon the bottom girder F of the press. The springs E are of suitable weight and length to secure the desired weighing of thebale, and I find in practice that good results are secured by using springs which will be about twelve inches long when extended and will compress to about six inches.

By the described construction it will be noticed a certain amount of cotton or other material tramped in the press will depress the weighing-bars to a certain point. In connection with such weighing-bars I provide means whereby the operator may be signaled when the desired amount of material-has been tramped into the box. This may be a bell operated in any desired manner or any other form of signal desired, and I do not desire to be limited in the broad features of myinvention to any particular form of signal. I have shown, however, a form of bell-signal which includes a rod or bar G, connected with one of the weighing-bars and suitably graduated, and a hammer is connected with and movable along said graduated bar, so it can be set to strike at different points, such hammer H being guided by a trip I to strike the bell J, a suitable spring h supporting the hammerhandle to effect the proper operation as desired. When the hammer is suitably located on the graduated bar Gsay at five hundred pounds-such hammer will, when five hundred pounds of cotton have been tramped in the box, ,be caused to sound the bell. Manifestly the bell may be located adjacent to the baling-box or otherwise where desired, and

instead of a bell any other form of audible, visual, or other signal may be employed.

In carrying out my invention in a singlebox press wherein the lint is pressed from below I may employ the construction shown in Figs. 6 and 7, wherein the false block or movable end I is arranged at the top of the baling-box and is carried on two or more upwardly projecting rods J, which extend through the top platen, one of the rods being extended and graduated to receive the arm K, which carries the bell-hammer. Springs L are arranged on the rods J and bear between the false block and the top platen of the press. In the operation of this construction,which is similar to that before described, the false block will recede as the cotton lint is fed into the box, and the signal will be sounded when the false block is adjusted to the proper position relatively to the weight of the desired hale, and the same combination of mechanism applied at the bottom of the press in a reversed position is used in singlebox down-packing presses.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

1. A baling-press provided with a weighing mechanism having a yieldingly-supported end piece or false block and signal devices arranged for operation by said end piece or false block and adjustable whereby they may be setin advance of or during the formation of the bale whereby to secure the sounding of the signal when the desired weight of bale is attained in the formation thereof, substantially as set forth.

2. A baling-press provided with a movable yieldingly-supported end piece or false block combined with signal devices arranged for operation thereby, whereby the recession of the end piece or false block to a desired degree will effect the operation of the signal devices substantially as set forth.

3. In a baling-press the combination of the bale-box, a receding end piece or false block therein and springs supporting said block combined with signal devices arranged for operation as the false block recedes substantially as set forth.

4. In a baling-press the combination of the baling-box, the weighing-bars provided with lugs projecting through the sides of and extending into said box, the springs supporting said weighing-bars, and signal devices substantially as set forth.

5. The combination with the baling-boX, the guide-bars having end extensions provided with notches or grooves, the weighingbars fitting at their ends in said notches or grooves and provided with lugs projecting into the baling-box, the springs supporting the weighing-bars, and signal devices substantially as set forth.

6. The combination with the baling-box provided with the stop-lugs,the weighing-bars extending alongside the baling-box and provided with lugs projecting into the balingbox, the false block supported on said lugs, the end bars provided with notches or grooves receiving the ends of the weighing-bars, the springs supporting the weighing-bars and signal devices substantially as set forth.

7. In a baling-press the combination of the baling-box, the weighing-bars and their supporting-springs, a rod or bar carried by one of the Weighing-bars, a hammer carried by said rod or bar, and a bell for operation by said hammer, substantially as set forth.

8. In a baling-press the combination of a movable end piece or false block, spring devices for supporting the same, a hammer arranged foroperation as the false block recedes and a bell substantially as set forth.

9. In a baling-press the combination of the baling-box having stop-blocks, the end bars secured to the ends of the box and extending beyond the sides thereof and provided in such extensions with notches orgrooves, the Weighing-bars having lugs projecting into the baling-box, the ends of such bars fitting in the notches or grooves of the end bars, the false blocks supported on the lugs of the weighingbars the springs supporting the weighing-bars and the signal devices all substantiallyas and for the purposes set forth.
